I am currently trying to export and obtain rasters of EVI for:
Every month of the year across 2000 to 2018 ie. If January has two MODIS EVI images, I would like to take the mean of the images for January and export one image for January 2000, and January 2001 and so on.
Similarly, I would like an averaged value of EVI for every month of the year across 2000 to 2018. In other words, a single EVI raster for January, a single EVI raster for February and so on.
I tried code provided in the answer here, but I am still unable to get a month by month as well as yearly average of EVI as needed above.
